Description

A kind of intelligent dedusting filtering bag
Technical field
The present invention relates to a kind of intelligent dedusting filtering bag, belong to dust arrester technical field.
Background technology
Between past 20 years, China accounts for gdp7-20% because of the loss that environmental pollution and ecological degradation cause, 2005, because of ring The conflict 5.1 ten thousand that border pollution causes, 2007,40% city domestic sewage directly discharged, and 60% large-size lake is because of ore deposit Material and Organic Pollution and eutrophication occurs, in 197 rivers of monitoring, half receives nitre sulphuric acid, permanganate and The severe contamination of oil, in 287 large- and-medium size cities of monitoring, the air quality only less than 1/10th reaches national ring The standard in guarantor portion, the economy of China continues with the rate of increase of telling of annual 9%, but development from now on be also faced with many huge Big obstacle, in addition to technological progress, maximum obstacle is exactly resource and the factor of environment, environmental pollution, and population pressure is made The excessive exploitation soil that becomes and use farming and animal husbandry land used, the pollution that desertification of land and modern industry manufacture.
Dust-removal cloth-bag can be rated as the heart of sack cleaner, commonly referred to as bag dust filter, dedusting filtering bag, dust collecting sleeve, laying dust Bag, dust settling pocket, dust-collecting bag etc..Dust-removal cloth-bag is the key component in sack cleaner running, usual cylinder type filter Bag is vertically hung in cleaner unit.Cleaner unit or cleaner are exactly the equipment that dust is separated from flue gas.And cloth Bag dust collector is also referred to as filtration dust catcher, is a kind of dry type high efficiency cleaner unit, and it is the pocket type being made using fibrous braid Filter element is trapping the dust arrester of solid particulate matter in dusty gas.Its action principle is grit when bypassing fiber cloth It is intercepted because inertia force effect is collided with fiber.In pulse and air-tank type pulse dust collector, dust is attached to filter bag Outer surface.When cleaner unit, dust is trapped in the outer surface of filter bag to dusty gas, and clean gas enter filter by filtrate Bag is internal.Cage within filter bag is used for supporting filter bag, prevents filter bag from subsiding, it contributes to the removing of dirt cake and again divides simultaneously Cloth.
The fabric of dust-removal cloth-bag and design should be pursued high efficiency filter as far as possible, be easy to dust stripping and effect durable in use.Remove Dirt cloth bag from most important, it directly affects the dust removing effects of cleaner unit, selection dust-removal cloth-bag from following several in terms of Selection is selected: the temperature of gas, wetness and chemical, granular size, dust content, filtration velocity, the factor such as clear dirt mode.
Sack cleaner is a kind of dry dust removal apparatus, and it is applied to, and trapping is tiny, non-fiber dust is dried.Filter bag is adopted Become with the filter cloth or nonwoven felt of weaving, the filtration using fabric is filtered to dusty gas, works as dust-laden Gas enters sack cleaner, and granule is big, heavy dust, and the effect due to gravity settles down, and falls into ash bucket, containing relatively When by filtrate, dust, by detention, makes gas be purified to the gas of fine dusts.
The efficiency of dust collection of typically new filtrate is not high enough.Filtrate using a period of time after, due to sieving, collision, delay, The effects such as diffusion, electrostatic, one layer of dust has been gathered on filter bag surface, and this layer of dust is referred to as bonding layer, in motor process after this, Bonding layer has become the main filtration layer of filtrate, relies on the effect of bonding layer, and the larger filtrate of mesh also can obtain higher filter efficiency. With dust filter material surface accumulation, the efficiency of cleaner unit and resistance all accordingly increase, when filtrate both sides pressure differential very When big, some can be attached to the tiny grit extruding past on filtrate, so that dust collector efficiency is declined.In addition, cleaner unit The too high air quantity that can make dust pelletizing system of resistance is remarkably decreased.Therefore, after the resistance of cleaner unit reaches certain numerical value, clear in time Ash.Bonding layer can not be destroyed, in order to avoid efficiency declines during deashing.
Sack cleaner structure is mainly by upper box body, middle part casing, lower part box (ash bucket), soot cleaning system and ash ejector The part such as structure forms.The quality of sack cleaner performance, in addition to correct selection filter pocket material, soot cleaning system is to sack cleaner Play conclusive effect.For this reason, ash removal method is to discriminate between one of characteristic of sack cleaner, it is also During Operation of Bag Dust Filter An important ring.
The application of dust-removal cloth-bag.The flue gas in iron-smelter, steel mill, ferroalloy works, fire resisting factory, Foundry Works, power plant etc. is controlled Reason dust pelletizing system.The smoke filtrations such as incinerator, coal-burning boiler, fluidized bed boiler.Bituminous concrete stirs, building materials, water The Workplaces such as mud pottery, Calx, Gypsum Fibrosum.The flue gas during smelting of aluminium electroloysis, lead, stannum, zinc, copper and other rare metals filters, micro- Thin material recycle, liquid, solid separation.The solid-liquor separation in the fields such as chemical industry, coke, white carbon black, dyestuff, pharmacy, plastic cement and superfine material Reclaim.The dust of mining, grain processing, flour, electron trade, timber processing etc. is administered and is purified and collects.
In dedusting filtering bag field, conventional monitoring of working condition scheme has monitoring at cleaner unit air intake vent to enter in cleaner unit Temperature, but do not monitor humidity and air pressure.
Content of the invention
For problem above, the present invention provides a kind of intelligent dedusting filtering bag, long service life, can intellectualized detection dedusting filter The data such as the temperature in dedusting filtering bag, humidity, dust concentration and pressure can be transmitted by the change of the physical property of bag, Realize dedusting filtering bag intelligent, can accurately judge positioned which dedusting filtering bag breakage simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: a kind of intelligent dedusting filtering bag, including dedusting filtering bag, Computer terminal, control module and sensor, described computer terminal, control module, sensor and dedusting filtering bag are sequentially connected, described Control module includes control module a, control module b and control module c, control module a be main control module, control module a with Computer terminal communicates, and control module b is from control module, and control module b controls control module c and communicates with control module a, Control module c is bottom control module, and the data that control module c is responsible for gathering sensor is communicated with control module b, control module A, control module b and control module c at utmost all can only control 60 submodules, and described sensor includes high-temperature temperature sensing Device, high Temperature Humidity Sensor and high temperature baroceptor, described sensor is sewn in dedusting filtering bag, described high-temperature temperature sensing Device, high Temperature Humidity Sensor and high temperature baroceptor are one group of data acquisition module.
